Violent crime doubled in Ross in 2012, but since there was only one violent crime there in 2011, it didn't take much for a statistical surge.

The violent crimes were an assault and a weaponless robbery, which involved a woman allegedly stealing cash and an iPhone from a Ross man she drove home from a club in San Francisco.

Ross had no violent crimes at all in six of the past 10 years, according to the state Department of Justice.

Property crimes fell from 36 in 2011 to 23 last year, less than half its level in 2004 and 2005.

"Our crime rates were down in most areas," said Ross police Chief Erik Masterson. "Violent crime is very low in Ross. The incidence of burglaries rose slightly, but thefts overall are down significantly.

"The burglary rate numbers may be affected by our new reports management system, which we use to account for all of our calls for service. We are doing a better job capturing accurate crime reporting and documentation."
